Spectroscopy and intruder configurations of $^{33}$Mg and $^{31}$Ne studied with antisymmetrized molecular dynamics
摘要：
用反对称分子动力学结合生成坐标方法研究了$^{33}$ Mg和$^{31}$ Ne的激发谱和中子单粒子组态.计算结果表明，两个核都具有强形变的$3/2^-$基态和$3p2h$组态.的激发光谱定性理解的Nilsson模型和计算表明，共存的小激发能内的不同入侵者的配置。计算得到的$^{31}$ Ne的单中子分离能很小（$S_n=250$ keV），表明它是一个具有强烈形变核的p波单中子晕。
英文摘要：
Excitation spectra and neutron single particle configurations of $^{33}$Mg and $^{31}$Ne are investigated by using antisymmetrized molecular dynamics combined with generator coordinate method. It is shown that both nuclei have strongly deformed $3/2^-$ ground state with a $3p2h$ configuration. The excitation spectra are qualitatively understood in terms of the Nilsson model and the calculation has shown the coexistence of different intruder configurations within small excitation energy. The calculated one neutron separation energy of $^{31}$Ne is rather small ($S_n=250$ keV) and implies a p-wave one neutron halo with a strongly deformed core.
